BRAKE LENING'.

Application tiled 4June 21,

To all whom it may concern:

Be it known that l, CHARLES W. BROWN, residing at Nashville, county of Davidson, State of Tennessee, a citizen of the United States, have invented certain new and useful Improvements in Brake Linings, ot' which the following is a specication.

rIhis invention relates to brake linings and is particularly adapted for use on the brake and transmission bands on automobiles of a popular make.

Great difficulty is 'experienced in the operation of some brake bands, particularly the brake and transmission bands of Ford automobiles due to the tendency of the linings to grab, thus causing the wheels to skid, `or to chatter thus causingv undue vibration to the engine and to the machine as a-whole.

lt is the primary object of this invention to provide an improved brake linin which is so constructed as to prevent boti chatter and grabbing and which will be eficient and effective to stop its drum and one which will have a long life.

Another object of my invention is the provision of a brake lining having a resilient body portion as of sheet cork or some similar acting substance and a protecting wear surface of a heavy exible material such as canvas and so formed asto permit the wearing away of one or more layers without havingthe brake drum in contact with the resilient body portion.

Referring to the drawing where preferred embodiments ot my invention are illustrated,

F ig. 1 is a longitudinal view of a section of my brake lining as viewed from the drum side.

F ig. 2 is a cross sectional view showing the drum side uppermost.

Fig. 3 is a view showing thev parts in place and folded before being fastened together.

Fig. 4 is a view similar to Fig. 3 but showl inga modified form;

ig. 5 is a view showing the brake lining in place in the band 'and ready tor installation.

Fig. 6 is'aview of three brake bands as the would appear in place on a Ford automo ile.,

Referring particularly to Figs. 1 and 2, 10 desi ates a'strip `or exible body portion suc as of cork or 'a similar substance.

ieee. serial .1w-569,869.

the body portion 10. rlhe cover 11 is folded v in any suitable manner as by having the outer lap fold up, over and under twice, (as at the left in Figli) while the other (right) side is folded under adjacent the body portion 10. Another way of placing the folds is as shown in Figure 4 where the -cover comes up on the one (left) side, Jiiolds over to the opposite side and back again on the outside and then letting the edge go under. After the folds are complete, the whole is fastened together in a suitable manner as for example, by the several rows of stitching 12 shown in Fig. 2.

In Figure 5, l have shown the brake lining in place within the brake band 13, at the ends of which are iliustrated the lugs 14 whereby the brake bands are caused to grip their respective drums.

rlhe position of the cork strip under the folds of heavy covering material, provides resiliency for the cover, thereby causing the pressure to be distributed. Since the cork does not come into contact with the brake drum, it does not burn out as is common in some other types of brake linings.

While I have described and claimed my invention as using canvas and cork in its construction, l desire to have it understood that any materials having similar characteristics may be used in place of the ones described.

`l/Vhile l have described, in detail, embodiments of my invention, desire to have it understood thatl do not limit myself to the exact structures described and that modiications and changes may be made without departing 'from the spirit of my invention and within the scope oir' the appended claims.

Having described my invention, what I claim is 1. A brake lining, comprising a non-metallic resilient body portion, a flexible' friction contacting portion between the body portion and the drum 'side the lining.

2. A. brake lining, comprising a non-metallic resilient body portieri, a 'tiexibie cover for the body portion for contacting with the drum.

3. A brake lining comprisin a body1 portion of cork, a, flexible brakerum contacting cover for the same.

4. A brake lining, comprising a body por- 5 tion of cork, a flexible cover for the body portion having a, plurality of layers of folds between the Wear surface and the body portion.

` 5. A brake lining, comprising a, body por- 10 tion of cork, e. flexible cover for the body portion having a plurality of layers of folds between the Wear surface and the body portion and means for securing the folds and body lortion together.

' 6. brake lining, comprising a body portion of cork, a, plurality of thicknesses of fabric between the body portion and the drum side of the lining.

)In testimony whereof I hereunto affix my signature.

CHARLES W. BRUWN.
